This is the Sierra 18-15102, a replacement serpentine belt for Mercruiser V8 engines. It measures 105" long and 13/16" wide. It replaces the Mercruiser number 57-865615Q06, which is the number to compare with the belt you are removing. Check the length and width against your old belt before you rely on it.
Our take
The 105" length and 13/16" width of the Sierra 18-15102 are the figures to check against the belt on your engine, since a serpentine belt has to match both. It is stated as a replacement for 57-865615Q06 on Mercruiser V8 engines.
